Surveillance & Intelligence Flashcards

Which type of surveillance involves gathering intelligence from human sources rather than technical means?

Answer: HUMINT

HUMINT (Human Intelligence) refers to intelligence collected through interpersonal contact and human sources.

A surveillance operative conducting a 'foot follow' in a crowded mall should primarily maintain what distance from the subject?

Answer: A distance that allows visual contact without arousing suspicion

The operative must balance proximity for visual contact against the risk of being 'burned' (detected) by the subject.

What is 'counter-surveillance' in the context of professional inspections?

Answer: Techniques used to detect whether one is being followed or observed

Counter-surveillance involves measures taken to detect or thwart surveillance being conducted against oneself or an asset.

Open-Source Intelligence (OSINT) gathering would include which of the following?

Answer: Reviewing publicly available social media profiles

OSINT involves collecting information from publicly available sources such as social media, websites, and public records.

When documenting surveillance findings, which principle is most critical for evidentiary value?

Answer: Maintaining a detailed, contemporaneous log with timestamps

Contemporaneous logs with precise timestamps establish a reliable chain of events and are far more credible as evidence.

Which behavior by a subject most strongly indicates they may be conducting counter-surveillance against an operative?

Answer: Making sudden direction changes and checking reflections in windows

Sudden direction reversals and reflection-checking are classic counter-surveillance detection maneuvers used to identify followers.

In mobile vehicle surveillance, the 'leapfrog' technique is used to:

Answer: Alternate lead vehicles to avoid detection by the subject

The leapfrog technique rotates which surveillance vehicle is the primary follower, reducing the chance that the subject notices a consistent tail.
